Description

Refrigerator capable of reducing touch input noise and control method thereof {REFRIGERATOR AND METHOD FOR CONTROLLING REFRIGERATOR CAPABLE OF REDUCTING TOUCH INPUT NOISE}

An embodiment of the present disclosure relates to a refrigerator capable of reducing touch input noise on a touch screen and a method of controlling the same.

A refrigerator is an electronic device for storing goods at low temperatures. For example, goods may include food, medicine, cosmetics, etc.

As refrigerators have become essential electronic devices in daily life, various user-friendly functions based on refrigerators are being provided. For example, a refrigerator is provided that has a touch screen mounted on the front and has the ability to input and output various information. A touch screen is a display-based input device configured to receive input (or touch input) when a user touches a specific part with a device such as a finger or stylus. Touch screens are also referred to as pointing devices. Touch generally refers to touching part of a touch screen with a finger or part of the hand.

The cooling function of a refrigerator is achieved by a refrigeration cycle consisting of a compressor, radiator, capillary tube, and evaporator. A compressor compresses refrigerant gas at high pressure. Refrigerant gas compressed to high pressure is a high temperature gas. Compressed refrigerant gas changes into a low-temperature liquid as it passes through the thin pipes of the radiator, releasing heat. Liquid refrigerant changes into a low-pressure liquid as it passes through a capillary (or expansion valve). The liquid refrigerant that passes through the capillary is a low-temperature liquid. The low-pressure refrigerant enters the evaporator, takes heat from the surroundings, and becomes a gas.

In the cooling operation of this refrigerator, the compressor operates at Rotations Per Minute (RPM), which is determined based on the difference between the current temperature value of the cold room or/and freezer room and the preset temperature value. It can be driven. For example, when the difference between the current temperature value of the freezer compartment of the refrigerator and the first set temperature value is 10°C or more, the compressor may be driven at a maximum number of revolutions per minute (eg, 3700 RPM). For example, when the difference between the current temperature value of the refrigerating compartment of the refrigerator and the second set temperature value is 6 degrees or more, the compressor may operate at a maximum number of revolutions per minute (eg, 3700 RPM).

The higher the revolutions per minute of the compressor, the more likely it is that power noise will be generated in the refrigerator's AC/DC power line. The generated power noise can be transmitted to each component of the refrigerator through the refrigerator's AC/DC power line. For example, power noise can be transmitted to components such as touch screens through AC/DC power lines. If power noise is transmitted through the AC/DC power line, touch input noise may be generated on the touch screen. When touch input noise occurs, the touch screen may malfunction, such as misrecognizing touch input.

When the compressor 102 operates at a maximum number of revolutions per minute (e.g., 3600 to 4000 RPM or maximum RPM), a power noise transmission path 104 as shown in FIG. 1B will be formed in the refrigerator 100. You can. The power noise transmission path 104 may be formed based on an Alternating Current (AC)/Direct Current (DC) power line connected to the compressor 102. This is because the components of the refrigerator 100 are connected to the same ground through the AC power source 110. Therefore, power noise is transmitted to the touch screen 72 connected to the AC/DC power line based on the power noise transmission path 104.

Figure 2 shows the power noise and touch transmitted through the AC/DC power line based on the power noise transmission path 104 when the compressor 102 operates at the maximum number of revolutions per minute (e.g., 3600 to 4000 RPM). This is an example of the waveform of noise detected on the screen 72.

3100 is an example of a voltage waveform detected on the touch screen 72 when power noise is transmitted through an AC/DC power line like 3000. Referring to 3100 in FIG. 3, no touch input is received through the touch screen 72, and a voltage close to 0 is detected on the touch screen 72. Therefore, when the operation of the compressor 102 is in the off state, misrecognition of the touch input does not occur on the touch screen 72.

The compressor 102 according to an embodiment of the present disclosure is a key component of the refrigerator 100 that determines the power usage and noise and vibration level of the refrigerator 100, which is turned on 24 hours a day.

The compressor 102 may be configured as, for example, a rotary type, a scroll type, or a screw type, but is not limited thereto.

The compressor control unit 101 according to an embodiment of the present disclosure controls the operation of the compressor 102. For example, the compressor control unit 101 controls the number of revolutions per minute of the compressor 102. The compressor control unit 101 according to an embodiment of the present disclosure may be configured according to the type of motor included in the compressor 102. For example, when the motor included in the compressor 102 is a stepping motor, the compressor control unit 101 may be configured in an open-loop control method. When the motor included in the compressor 102 is not a stepping motor, the compressor control unit 101 may be configured by a closed-loop control method or a feedback-loop control method. The compressor control unit 101 may be referred to as a compressor driving unit.

When a signal (or triggering event) indicating reception of a touch input is received from the touch screen 72 through the transmission line 103, the compressor control unit 101 according to an embodiment of the present disclosure sends a response signal indicating that the signal has been received. It may be configured to transmit to the touch screen 72.

When a signal (or data or triggering event) indicating reception of a touch input is received from the touch screen 72, the compressor control unit 101 according to an embodiment of the present disclosure changes the RPM of the compressor 102 on the touch screen 72. It can be controlled at an RPM that reduces touch input noise. For example, the compressor control unit 101 may control the number of revolutions per minute of the compressor 102 to the lowest RPM or 0 RPM (operation of the compressor 102 is turned off). The RPM of the compressor 102 may be referred to as the number of revolutions. The compressor 102 may rotate at an RPM controlled by the compressor control unit 101. The fact that the compressor control unit 101 controls the RPM of the compressor 102 may indicate that the compressor control unit 101 determines the RPM of the compressor 102. The compressor 102 may operate based on the RPM determined by the compressor control unit 101.

The compressor control unit 101 may control the RPM of the compressor 102 based on the difference between the temperature value of the freezer compartment 12 of the refrigerator 100 and the first preset temperature value. The first set temperature value represents the reference temperature value for the freezer compartment 12. The reference temperature value for the freezer 12 may be a value set when manufacturing the refrigerator 100. The reference temperature value for the freezer 12 may be a value set by the user.

The compressor control unit 101 may control the RPM of the compressor 102 based on the difference between the current temperature value of the refrigerating compartment 13 of the refrigerator 100 and the second preset temperature value. The second set temperature value represents the reference temperature value for the refrigerating compartment 13. The reference temperature value for the refrigerator compartment 13 may be a value set when manufacturing the refrigerator 100. The reference temperature value for the refrigerating compartment 13 may be a value set by the user.
